IMPROVEMENT IN FASTENINGS FOR BOXES, &c.

To all whom it may concern:

Beit known that I, J oHN J AMES GREENOUGH, of Syracuse, in the county ofOnondaga and State of New York, have invented certain new and usefulImprovements in BoX-Fastenin gs 5 and do hereby declare the following'to be a full, clear, and exact description thereof, reference being hadto the accompanying' drawing and to the letters of reference markedthereon.

The nature of my invention consists in the construction and arrangementof a curved-lip button, eccentrically pivoted and used in combinationwith a catch of suitable as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, whichforms part of this specication, and in which- Figure l is a front viewof the box fastening. Fig. 2 is a rear view of the curved-lip button.Fig. 3 is a transverse vertical section through the center of Fig. l;and Fig. 4 shows various forms of catches that may be used with thebutton.

A represents a round piece of this metal punched out, of the desiredsize, in whicha notch, a, is cut. This blank or round piece of metal issubmitted to the action of a die, which stamps it into form andimpresses its face with any iigure engraved on the die, 'and at the sametime turns its edge all around, thus forming the construction,m

to these',

curved lip b, as shown in Fig. 2. The notch c leaves an open space inthe lip or rim b, and a hole, f, is made through this button near thecenter, for the pin or stud upon which it is to turn. This hole shouldbe a very little further from the notch t than from the opposite side,thus giving a slight eccentrieity to the revolution of the catch, whichcauses it to draw gradually upon the knob or catch to tighten its hold,and hold the cover rmly down to its place. A catch or hook of anydesired construction may be used. In Fig. 4 I have represented threedifferent forms, y z,- but I do not confine myself as they may be madein any convenient l manner. The button A should generally be pivloted tothe body of the box, and the catch fastened to the lid 5 but it is, ofcourse, immaterial it' this order should be reversed.

The box-fastening thus constructed may be made of various sizes, to suitthe purposes for which the same may be used.

Having thus fullyv described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

The curved-lip button A with notch a, constructed as described, andturning on a pivot, in combination with a catch of suitable construction, substantially as and for the purposes herein set forth.
